卷毛紫金牛(Ardisia japonica)的煎剂一般用于治疗咳嗽和子宫出血。为了探索新的天然活性成分,对卷毛紫金牛的成分进行了分离和鉴定。取卷毛紫金牛的地上部分,依次以石油醚,氯仿和甲醇提取。甲醇提取物用正丁醇和水分配提取,将得到的正丁醇组分上Sephadex LH-20柱,进行氯仿-甲醇-水-正丙醇-乙醇(9:6:8:1:8,液滴反流色谱法下行)层析,得到3种皂甙1～3,并确定化合物中共含一个由4个糖链组成的 The decoction of Ardisia japonica is generally used to treat cough and uterine bleeding. In order to explore new natural active ingredients, the components of the curled purple Jinniu were isolated and identified. The aerial parts of the curled purple gold bull were extracted with petroleum ether, chloroform and methanol in order. The methanol extract was partitioned and extracted with n-butanol and water. The resulting n-butanol fraction was applied to a Sephadex LH-20 column and subjected to chloroform-methanol-water-n-propanol-ethanol (9:6:8:1:8, liquid). Chromatography was performed by DTC chromatography to obtain 3 saponins 1 to 3, and it was confirmed that the compound contained a total of 4 sugar chains.
